Abstract: CONTINUOUS BIAS CONTROL FOR ELECTROGRAPHIC           DEVELOPMENT APPARATUS                 Abstract of the Disclosure Apparatus for use in an electrographic development station having a long development zone, for example, having two magnetic brushes mounted in tandem.  The apparatus con-tinuously senses an electrostatic charge pattern and applies an electrical bias to the development station which corresponds to the intensity of the sensed charge.  The application of the bias is delayed until the charge pattern passes  the last development portion of the zone, for example, the second mag-netic brush.  In a preferred embodiment, the charge pattern is sensed by an indication plate coupled to an amplifier which provides a signal to a Pade' pure time delay circuit.  The delayed signal drives a high voltage bias amplifier which accordingly biases the development station.  The delay is chosen to correspond to the time it takes the sensed pattern to pass the later portion of the development zone.

Abstract: ABSTRACT OF THE DISCLOSURE:          An electrical contact for joining the conductor of an insulated cable to a further electrical terminal point such as a DIP plug, a printed circuit board card, a flat cable, etc.  The upper portion is formed in a cylindrical configuration with two upstanding arms spaced apart at two colinear points on their circumference to provide an insula-tion piercing slot and a strain relief slot.  The free ends of the upstanding arms are pointed to permit the contact to pierce the insulation about a conductor and allow one slot to make a good electrical joint with the conductor itself while the other slot grips the conductor insulation to pro-vide strain relief.  A properly configured tail portion per-mits the connector to be appropriately coupled to a terminal point.

Abstract: ABSTRACT OF THE DISCLOSURE             An internal combustion engine, which has sound-proofing cowling, uses the space between the sidewalls of the cylinder block and the cowling to provide a reservoir for a liquid lubricant media.  A cover cap is provided over the fuel injection and valve timing mechanisms, and the space between the cover cap and the cowling, which is over the top of the cylinder head, provides a chamber for receiving coolant form the engine cooling system.  The large surface area of the cowling along the sides of the cylinder block accommodates the transfer of heat from the lubricant to the atmosphere.  In addition both the lubricant and the coolant serve as sound deadening medias in the sidewall reservoirs and in the overhead chamber.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for slicing onions and other hard vegetables.          The apparatus comprises carrier means mounted for movement through a cutting path in a first direction.  A plurality of cutting blades is disposed within the path in a downwardly descending ramp.  Each of the blades includes a leading edge and a trailing edge, with the leading edge forming the cutting edge of the blade.  The blades are sequentially offset from one another in said one direction and parallel to one another in the direction normal to said one direction, with the leading edge of one blade spaced from the trailing edge of the preceding blade by a distance at least equal to the thickness of the blade.         The carrier means serves to carry the vegetable through the path and into sequential contact with succeeding blades to effect the sequential slicing of the vegetable.         The carrier means comprises a base for supporting the vegetable and a pusher member.  The pusher member is arranged to apply a force on the vegetable at an area thereon opposite to the blade then in contact with the vegetable to force the vegetable cleanly through the blade.  The pusher member is preferably curved and is arranged to pivot as the carrier moves along the cutting path while making contact with the base at all times to preclude any portion of the vegetable from falling out of the carrier.

Abstract: PROCESS AND APPARATUS FOR CONVERTING      SOLID WASTES TO PIPELINE GAS              Abstract of the Disclosure Solid waste is fed to a confined zone under pressure and contacted with hydrogen containing gas.   Partial conversion of the solid waste to methane occurs and the methane containing gas mixture is removed from the confined zone; it is subsequently purified and methanated so as to be a replacement for natural gas.          The remainder of the solid waste is discharged from the confined zone as a carbon containing char which is delivered to a separate reaction zone where it is con-tacted with steam and oxygen under pressure to convert it to synthesis gas (a mixture of hydrogen, water vapor, carbon monoxide and carbon dioxide).  The synthesis gas is drawn from the reaction chamber and serves as the hydrogen feed gas into the confined zone.  Between the two zones, metal and glass are separated from the char by virtue of their much higher density than the carbon-aceous char by entrainment of the char in a jet of steam.

Abstract: BALANCED VALVE WITH PRESSURE SENSING MEANS            Abstract of the Disclosure An improved balanced valve includes a body having a cylindrical valve chamber and a pair of flow passages intersecting the lower portion of the chamber. An annular valve seat is located between the lower portion and a first of the flow passages and is coaxially aligned with the cylindrical valve chamber. A main valve disc assembly is mounted for axial movement within the cylindrical valve chamber for selective engagement of a main disc thereof with a seat and further includes a concentric hollow body extending from the main disc away from the seat and terminating at a piston fitting which is slidably received within an upper portion of the cylindrical valve chamber. A coaxially aligned valve stem extends from an operating mechanism located above the valve through the upper portion, the piston fitting and the hollow body to terminate at an auxiliary valve disc. An axial opening through the main valve disc assembly allows communication between a region above the disc assembly and a region below the main disc to substantially control fluid forces acting on the opposite sides of the main valve disc assembly to facilitate opening and closing of the valve. Control of the fluid forces is partially obtained through predetermined axial positioning of the auxiliary valve disc during operation of the valve stem to open and close the axial opening through the main valve disc assembly. The improvement includes a radial array of pressure sensing passages in the main disc which extend from the axial opening to a peripheral region of the disc below the seating surface of the disc. As fluid flows from the second to the first flow passage, as when there is a rupture of the first flow passage, an upward force is generated on the main disc just prior to closure which tends to resist the closing force on the valve. The pressure sensing passages allow a higher fluid pressure to be communicated to the region above the main valve disc assembly to effectively oppose this resistance to closure.

Abstract: METHOD OF FORMING GLASS FIBERS                      Abstract of the Disclosure An improved method for the formation of glass fiber strands is disclosed.  Air passing downwardly with the filaments is prevented from returning to the region directly below the bushing and thus prevented from causing air turbulence below the bushing.  This is accomplished by venting air which strikes the floor of the filament formation level of a double level filament forming and winding operation away from the region under the bushing.  By preventing air turbulence below the bushing, improved filament formation can be achieved.
